Betsy

Twenty-three, and she will tell you the afternoon suits her better than any hour after midnight ever did. Her quarter is full from ten onwards: the trams, the queues, the tour groups, all of it under the window. None of that reaches the fourth floor, and the contrast is part of what people are booking. Soapy and nuru she prefers before four, while a bathroom is warm and nobody downstairs is thinking about it. Czech and English are both on offer and she uses whichever one gets a sentence across faster.

Betsy decides which bookings she takes and may decline any of them; she sets the limits for what a session includes, says what they are, and may end a visit at any point, as the terms set out.
